Abstract
Most researches to modeling wave propagation in shallow water are using two class of waves, non linear
shallow water wave equation as gravity wave equation, and simple wave equation as compressional wave
equation. In this research, wave propagation over mangrove models was conducted. The aim o f this research
were to study velocities and dispersion effects of wave propagation where propagate toward the mangrove
models. The first order accuracy of the explicit finite-difference method was used to approximate the gravity
wave equation and the second order accuracy of the explicit finite-difference method. It was used to approximate
the compressional wave equation. Variety of water depths, 5 m up to 100 m are used to simulate the wave
propagation. Results of non linear wave propagation also are compared with a result of compressional wave
propagation. The mangrove models are employed for different water depths and different wave equations.
Results of this research present that if the water depths increase from 5 m up to 100 m, the wave velocity will be
increases significantly. For the same values of water depth, equal to 5 m, compressional waves propagate faster
than gravity waves. For deeper water depths, the dispersion effects are less than for shallow water depths.
